PUNCHING APPARATUS.

To all whom it may concern:

Be it known that I, AN'roNE J. Snr'rnn, a citizen of the United States,residing at Cattaraugus, in the county of Gattaraugus and State of NewYork, have invented certain new and useful Improvements in PunchingApparatus; and I do hereby declare the following to be a full, clear,and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same,reference being had to the accompanying drawings, and to the letters andfigures of reference marked thereon, which form a part of thisspecification.

This invention relates to new and useful improvements in apparatus forcutting disks of wood, paper, metal or other material from solid sheetsand comprises series of punches mounted upon a cross head and movableagainst the punching surfaces, the punches being mounted in multiple andat an angle of preferably 45 degrees to the line of feeding of thesheet.

The invention comprises various details of construction, combinationsand arrange' ments of parts which will be hereinafter fully describedand then specifically defined in the appended claims.

I illustrate my invention in the accompanying drawings, in which Figure1 is a top plan view of a punching apparatus embodying the features ofmy invention. Fig. 2 is an end elevation, parts being in section. Fig. 3is an enlarged detail in elevation showing the ratchet feed mechanism.Fig. 4 is an enlarged detail sectional View longitudinally through apunch and a head block and feeding block, and Fig. 5 is a detail viewshowing a sheet of metal partially punched. Fig. 6 is a detail in topplan view. Fig. 7 is an edge View of the construction shown in Fig. 6.

Reference now being had to the details of the drawings by letter, Adesignates the frame of the apparatus having a driving shaft B mountedin suitable bearings in said frame, and C designates a pitman connected.to the crank of the driving shaft and connected to a link O which inturn is fastened to an arm D of the cross head D, which lat ter isadapted to reciprocate in the guide blocks E forming a portion of theframe of the apparatus. Suitable adjustment screws Specification ofLetters Patent.

Serial No. 516,084.

E are mounted in said block for the purpose of regulating the play ofthe crosshead.

Mounted upon a laterally projecting arm D of the crosshead is a seriesof punches F, an enlarged detail view of one of which is shown in Fig. 4of the drawings, and which punch is mounted in a socket d with anaperture in its bottom through which an adjusting screw d passes, thehead of said screw resting upon the bottom of a recess G formed in thelaterally projecting portion D of the crosshead. A jam nut G is mountedupon the threaded portion of said adjusting nut in the manner shownclearly in Fig. 4 of the drawings. A set screw H is mounted in athreaded aperture in the wall of each socket and is adapted to bearagainst and hold the shank portion of the punch in an adjusted position.Said punch is hollow and has an opening in its circumference as at Daffording means whereby the disk, as it is cut from a sheet, may makeexit. Fixed to the laterally projecting arm D of the crosshead is anapron D positioned underneath the exit opening in the punch and affordsmeans whereby the disk, as it is cut, may be defiected away from thecrosshead, and opposite the apron D is a similar apron I fastened alsoto a laterally projecting portion of the crosshead and upon which thewaste pieces are adapted to fall as they are severed from the sheet.

Mounted in suitable bearings upon the frame of the two feeding rollers Kand K, the former of which has spindles which are mounted in boxes inthe elongated opening N forming a part of the frame, and a set screw Jis mounted in the lower end of the roller K and has a jam nut J mountedthereon, said screw J being adapted to adjust the lower bearing box inwhich the spindle of the roller K is mounted. An adjusting screw 0 ismounted within the opening N and upon which the boxing L of the roller Krests and an adjusting screw L bears against the upper end of the box Land a coiled spring L is interposed between a nut L and the top of thebox L.

Fixed to the shaft K is a ratchet wheel Q, and Q designates an arm whichis journaled upon the spindle of the roller K and carries a pawl Qadapted to engage the teeth of the ratchet wheel. A spring pawl Q isfixed to the frame and engages the teeth of the ratchet Wheel and isadapted to prevent a reverse rotary movement thereto. A rod R is pivotedat one end to the arm Q and its other end is fastened to an eccentricand affords means whereby the feeding of the sheet T upon the table Smay be regulated. A presser roller M is mounted in a boss M upon theframe and a spring M serves to hold the presser roller down against thesheet to be punched. A head block, designated by letter 1 is mountedupon the frame and recessed as at P for the reception of the punch as itmoves upward and co operates with the marginal edge of the head blockfor punchin the disk.

Referring to Fig. 1 of the drawings, it will he noted that a guide W isprovided and is shown as adjustable, whereby it may be moved to ada tthe same for use in cut.- ting disks of di erent sizes. Bolts W aremounted upon the guide and adapted to ass through the elongated slotsand afford means for holding the guide member in ad justed position.

What I claim to be new is 1. A punching apparatus comprising a frame, adriving shaft journaled therein, a vertically movable crosshead, pitmanconnections between the same and said shaft, a series of punches mountedupon a laterally projecting portion of said crosshead, a head blockpositioned over said punches, a table having an inclined edge which isscalloped and positioned adjacent to said punches, feed rollers, andmeans for imparting an intermittent rotary motion thereto.

2. A punching apparatus comprising a frame, a driving shaft journaledtherein, a vertically movable crosshead, pitman connections between thesame and said shaft, a seriesof punches mounted upon a laterallyprojecting portion of said crosshead, a head block positioned over saidpunches, a table, an adjustable guide upon the table, feed roll ers,said table having an inclined edge which is scalloped and positionedadjacent to the punches.

8. A punching apparatus comprising a frame, a driving shaft journaledtherein, a vertically movable crosshead, pitman connections between thesame and said shaft, said crosshead having a laterally projecting armwith recesses therein, a set screw mounted in a threaded aperture in thebottom of each recess and having its head resting upon the wall of anopening in said laterally projecting part, a punch having a shankportion mounted in each of said recesses and against which said screw isadapted to bear, recessed head blocks positioned above the punches, atable, an adjustable guide upon the table, and feed rollers.
